For the Guarantee Conditions, see the

Vetus Diesel ‘Service and Warranty

Manual’ (320199.05).

This engine has been built exclusively

for the application specified in the scope

of supply and is to be used only for the

intended purpose. Any use exceeding

that scope is considered to be contrary to

the intended purpose. The manufacturer

will not not assume responsibility for any

damage resulting there from. The risks

involved are to be borne by the user.

Use in accordance with the intended

purpose also implies compliance with the

conditions laid down by the manufacturer

for operation, maintenance and servic-

ing. The engine should only be operated,

maintained and serviced by persons who

are familiar with the former and the haz-

ards involved.

The relevant accident prevention guide-

lines and other generally accepted safety

and industrial hygiene regulations must

be observed.

Unauthorized engine modifications will

invalidate any liability claims against the

manufacturer for resultant damage.

Manipulations of the injection and regu-

lating system may also influence the

performance of the engine, and its emis-

sions. Adherence to legislation on pollu-

tion cannot be guaranteed under such

conditions.

Warning indications

1 Safety measures

Do not smoke if refuelling.•

Avoid spilling fuel on hot surfaces. Spilled•

fuel must be cleaned up immediately.

Do not use petrol or diesel to clean com-•

ponents but make use of good quality,

non-inflammable, non-poisonous sol-

vents that are available from dealers.

Always be alert to possible fuel or oil•

leakage!

If you discover a leak, take counter-

measures immediately. If fuel or oil is

spilled on a hot engine, fire can break

out. This can cause physical injury or

damage to the equipment.

Do not fill the fuel tank while the engine•

is running!

Only refuel with the engine stopped.

Never put flammable materials in the vi-•

cinity of the engine!

Keep the engine and engine compart-•

ment clean!

Remove all inflammable materials such

as fuel, oil and other litter before it builds

up in the vicinity of the engine.

Connecting (emergency) extra starting•

battery

Proceed as follows when an extra start-

ing battery is used to jump start the en-

gine:

First connect the positive lead-

Lastly connect the earth cable (nega--

tive pole) to the engine block

If this cable is connected in error to the

negative pole of the engine battery, a

spark can occur. The result of this could

be that explosive gas produced by the

battery explodes.

Once the engine is started, first re--

move the earth cable.

Preventing fire and explosion

Fi r e r i s k !

1 Safety measures Prevention of injury

The moving parts of the engine are dan-•

gerous. Never touch moving parts of the

engine while it is running, to prevent cuts

and other injuries.

Stop the engine before carrying out•

maintenance!

Always stop the engine before topping•

up or replacing fuel, oil or coolant.

Before carrying out inspection or mainte-•

nance, the ignition key must be removed

and the main battery switch turned off.

Satisfy yourself that everything is in or-•

der before the engine is started again!

Make sure that no-one is working on or

close to the engine before you start it.

Remove all foreign objects from around

the engine, such as litter, oil, tools and

other components that are not part of

the engine.

Install all protective covers!•

To prevent injury, make sure that all pro-

tective covers and cover plates are re-

placed over moving parts.

Remove any tool used to bar the engine.•

If you leave this in position, serious injury

or damage to the equipment can be the

result.

NEVER open the cap of the expansion•

tank when the engine is at working tem-

perature.

Only check the level of the coolant after•

the engine has been stopped and the

cap of the expansion tank is cool enough

to remove with bare hands.

1 Safety measures Prevention of injury

Be careful with battery acid!•

If battery acid comes in contact with the

eyes or skin, rinse the affected part im-

mediately with copious amounts of wa-

ter. If battery acid comes in contact with

the eyes, rinse them out immediately with

plenty of water and consult a doctor.

Be careful with antifreeze!•

If you accidentally swallow antifreeze,

make yourself vomit and consult a doc-

tor immediately. If antifreeze comes in

contact with your eyes, wash them out

immediately with plenty of water and

consult a doctor.

Make sure that you are wearing suitable•

clothing before starting work!

For your own safety you will most likely

need special equipment - safety helmet,

eye protection, safety boots, safety gog-

gles, heavy gloves, ear protectors etc.

Use them when necessary.

Carry out maintenance procedures safe-•

ly by only using suitable tools.

Exhaust gases•

Do not start the engine if the exhaust

system is not connected.

When the engine stops suddenly:•

If the engine stops suddenly, do not start

it again immediately. Track down the

cause and carry out the necessary re-

pairs before you start the engine again. If

you do not do this, serious engine prob-

lems can develop.

If the oil pressure is too low:•

Stop the engine immediately and check

the lubrication system. Running an en-

gine with low oil pressure can cause

bearing and other parts to seize.

If the engine overheats:•

If the engine should overheat, do not

switch it off immediately. If an overheat-

ed engine is stopped suddenly, this can

cause the coolant temperature to rise

rapidly and moving parts to seize. First

let the engine run in neutral to allow the

hot parts of the engine to cool down,

stop the engine and allow it to cool,

and then gradually top up the coolant.

Remember: adding coolant to an over-

heated engine can cause damage to the

cylinder head.

If the drive belt has broken:•

Stop the engine immediately. If an en-

gine is running with a broken drive belt

this can result in the engine overheating

and in turn to coolant squirting out of the

expansion tank.

If the engine behaves strangely:•

Stop the engine or reduce the speed as

far as possible.

Do not use the engine again until the

cause of the defect has been solved.
